From a548792aa0beef4330a3d47eb75dd2fe741013bc Mon Sep 17 00:00:00 2001 From: Andrew Kreiling Date: Sun, 3 Mar 2013 07:50:59 -0600 Subject: Don't blindly call blame_file! on exceptions in ActiveSupport::Dependencies::Loadable It is possible under some environments to receive an Exception that is not extended with Blamable (e.g. JRuby). ActiveSupport::Dependencies::Loadable#load_dependency blindly call blame_file! on the exception which throws it's own NoMethodError exception and hides the original Exception.
